Egg shells will become transparent after adding vinegar. The experimental principle is that eggshells contain calcium carbonate and white vinegar contains acetic acid. Calcium carbonate is insoluble in water, but can react with acetic acid to produce calcium acetate and carbon dioxide. Eggshells soaked for a long time will be completely dissolved in vinegar, leaving only insoluble eggshell inner membrane. Therefore, this film of eggs makes people mistakenly think that the eggshell has become transparent.
